About GLB Model Viewer
GLB Model Viewer is a free, browser-based tool from XO3D Labs. Upload and inspect GLB files online with local 3D preview, PBR materials, HDRI lighting, background colour, camera controls and a copyable model summary. It is built for 3D artists, CGI generalists and technical artists, runs entirely in your browser with no signup or install, and is one of 70 free tools in the Labs suite.
What it does
GLB Model Viewer lets you upload a GLB file and inspect it in a browser-based 3D viewer with orbit controls, PBR materials, default environment lighting, optional custom HDR lighting, background colour, fullscreen and zoom controls. After upload it also shows a local inspection summary with file size, mesh count, material count, approximate triangle count, model bounds and practical next checks.
How to use it
Drop a .glb file onto the viewer or click Upload Model. Use Custom HDR to test reflections, choose whether the HDR applies to the model or the whole scene, adjust the background colour, reset the camera, zoom or enter fullscreen. Copy Summary exports the local model summary without asking for email.
How to read the result
Use the summary as a quick inspection aid before sharing or publishing a model. Check whether materials appear, whether reflections respond to HDR lighting, whether the triangle count is suitable for the target device, and whether the model frames cleanly from the default camera. Files stay in the browser and are not uploaded to XO3D.
